Longevity of RW |
|
|
After a bit of experimenting, I settled on DVD+RW as my ppreferred
type of disk for DVD authoring.
This is largely to do with compatibility betwen different drives; my
Sony Vaio (yes, I know ...) is extremely unwilling to read DVD+R or
DVD-R and is a bit iffy with DVD-RW :-(
I was talking to a colleague at work about it recently, and he said
that DVD+RW is not a good format for keeping stuff for a long period,
because the dye is designed such that it can change its properties
easily (so as to be e-written), and that it would naturally
deteriorate in a comparatively short space of time.
Well, he's known to be a first-class bulshitter, but it does sound a
little convincing.
Should I make DVD+R copies of my stuff?
They might outlast the Vaio anyway :-)

Interesting, indeed.
"The alloy film is not as stable as the dye used in R discs because
the material normally degrades at a faster rate ...", which seems to
support Mark's claim.
"... however, these discs should still be stable enough to outlast the
current CD or DVD technology" - so I may not have to rush to
re-archive my stuff just yet :-)
Thanks, Phil!
